Amazon PPC Audit Checklist: 15 Things to Check to Cut Wasted Ad Spend

Most Amazon advertising accounts are leaking money — and most sellers do not know where. Campaigns get launched, bids get adjusted when something looks off, and a year later the account is a tangle of overlapping keywords, forgotten auto campaigns and budgets that no longer match the goals. A structured Amazon PPC audit finds that waste and turns it into profit. Here are the 15 things our team checks first when we audit an Amazon Ads account, so you can run the same review on yours.

Why Run an Amazon PPC Audit?

Amazon Ads rewards constant attention. Search behavior changes, competitors adjust their bids, and new ad formats appear. An audit gives you a clear picture of what is working, what is wasting budget and where the biggest growth opportunities are. Brands typically run a full audit every quarter, and before big events like Prime Day and Q4.

Part 1: Goals and Metrics

1. Do You Know Your Break-Even ACOS?

Your break-even ACOS equals your profit margin before advertising. If you make 30% margin, a 30% ACOS means ads are breaking even. Every product should have a target ACOS based on its margin and goal — launch, growth or profit.

2. Are You Tracking TACoS?

ACOS only looks at ad-attributed sales. TACoS (total advertising cost of sale) compares ad spend with total revenue and shows whether ads are growing your whole business. Read our guide on ACoS vs TACoS for details.

3. Is Spend Concentrated on the Right Products?

Check how your budget is split across ASINs. Often a large share of spend goes to products with low margins, weak reviews or poor stock levels, while hero products are underfunded.

Part 2: Campaign Structure

4. Is Your Account Structure Clear?

A good structure separates campaigns by product group and match type (auto, broad, phrase, exact and product targeting). When everything is mixed together, you cannot control bids or budgets properly.

5. Are Keywords Competing Against Each Other?

The same keyword in several campaigns means you are bidding against yourself and splitting data. Use negative exact keywords to make sure each search term is controlled in one place.

6. Are Winning Search Terms Being Harvested?

Auto and broad campaigns are for discovery. Search terms that convert well should be moved into exact match campaigns where you control the bid — and added as negatives in the discovery campaign.

7. Are You Using All Three Ad Types?

Sponsored Products drive most sales, but Sponsored Brands (including video) build brand awareness at the top of search, and Sponsored Display lets you retarget shoppers. Brands that only use Sponsored Products leave reach on the table. See our Sponsored Brands video guide.

Part 3: Wasted Spend

8. Search Terms with Spend and No Sales

Pull your search term report for the last 60 days and sort by spend. Terms with meaningful spend and zero orders are usually your biggest and quickest savings. Add them as negatives or lower the bids.

9. Irrelevant Product Targets

Auto campaigns often show your ads on unrelated product pages. Review the ASINs you are appearing on and negate the ones that do not convert.

10. Bids That Have Not Been Updated

Bids set months ago rarely match today's competition. Keywords above target ACOS need lower bids; profitable keywords with low impression share may need higher ones.

Part 4: Growth Opportunities

11. Budget Caps on Profitable Campaigns

If profitable campaigns run out of budget by mid-afternoon, you are missing sales you could be making at your target ACOS.

12. Brand Defense

Search for your own brand name on Amazon. If competitors' ads appear above your products, you need branded campaigns and defensive product targeting on your own listings.

13. Competitor Targeting

Target competitor ASINs where your product has a clear advantage — better rating, better price or better features. This can win customers who are already ready to buy.

14. Placement and Dayparting Data

Compare performance for top of search, rest of search and product pages. Adjust placement bid modifiers where one placement clearly converts better.

15. Listing Quality Behind the Ads

High ACOS is often a conversion problem, not an advertising problem. If a keyword gets clicks but no orders, check the main image, price, reviews and bullets. Our listing optimization checklist helps here.

Frequently Asked Questions

How often should I audit my Amazon PPC account?

Review search terms and bids weekly, and run a full structural audit every quarter and before major sales events.

What is a good ACOS on Amazon?

It depends on your margin and goal. A launch product may run above break-even to build rank, while a mature product should run below break-even to stay profitable. There is no single "good" number for every brand.

Can I audit my account myself?

Yes — this checklist is a strong starting point. An experienced PPC team will usually find more, faster, because they know the patterns that waste money across many accounts.

Final Thoughts

A PPC audit is the fastest way to lower ACOS and scale profitable sales. Even fixing a few of the 15 points above can free up budget you can reinvest in what is already working.
